Cold Weather Concrete
Get Ready
•Initiate an action plan for cold weather concreteing to include on/in ground and above ground placements
•Never place concrete on frozen ground - enclose area and heat or use insulating blankets prior to placement to increase temperatures to at least 50°F.
•Use insulating forms for above ground placements.
•Never use unvented heaters in enclosed placement areas.
•Use accelerating admixtures as needed.
•Increase cement content of concrete mix - +/-100 lbs / cubic yard

This Years Winner!
2016 Commonwealth Award Winner: Stone Brewery.


Located in the heart of Richmond, The building architecture brings a mix of Raw Industrial and Modern Style that maintains the roots of the Richmond Tobacco Warehouses and is consistent with Stone’s Culture. The Exposed Steel, reclaimed wood and stained concrete finish blends with the natural surroundings making it an inviting setting. The Stone Brewery’s 220.000Sq-ft manufacturing plant might look like a warehouse from the outside, but from the inside it is clear that the facility is carefully designed to produce 600,000 barrels of beer per year. By using precast panel construction for the exterior walls, the team was able to erect the steel and place the 79,000 SF of Insulated Precast Cladding Panels around the entire 216,000 SF building in just less than 4 weeks.


Utilizing the 3D, Building Information Model (BIM) that contained the complex building structure, precast panels, MEP systems, process piping, etc, the team was able to streamline the coordination of the complete design and construction team and brewers especially when communication was across multiple time zones, VA, Calif, and Germany. The brownfield site previously was a concrete mixing plant and staging area which included an old dumping ground, consists of a 14 acre “tank farm”, featuring elevated 400,000lb brewing tanks. To ensure these tanks would not move laterally, a 5ft- thick concrete deck was installed. The deck beams contain 118 tons of rebar, including #12 and #14 bars, at 6” on center.

Hot Weather Concrete
Are you prepared?

It's only early March and we already have temperatures reaching or exceeding 80 F. You know what that means, the 100 F days are only a few short months away. Are you prepared for placing concrete in the sweltering summer months? Don't know how to keep your cool when it comes to placing concrete in the summer?

Then you may want to check out the information in ACI 305.1-14.

If you have questions about masonry and hot weather check out ACI 530.
